    I have a preamp with built in crossover (Alembic F-1x). I was thinking of sending the top end signal to my ratty old ampeg guitar amp, but do not want to blow the speaker.

    Any suggestions for a safe range of frequencies to send to guitar combo?

    The lower end of a guitar is an octave higher than 4 string bass, so guitar amps are designed to handle frequencies that low. However, most guitar amps start to roll off before 82Hz (guitar low E), so if you want a solid bottom you are going to want to crossover higher. One note – it’s a tricky thing crossing over in the middle of the fundamental range. You’re going to get a very noticeable change in tonality across the range, but maybe that’s what you are looking for.

    I have done this before. Try crossing over at roughly 400hz. You will keep all the punch in the bass setup and the clarity in the guitar amp. Actually, I would run a full sound on the bass amp and just roll off the lows on the guitar amp. This is what I did. It worked better and sounded more natural.
